Unstable weight of PVA injection molded products
Sorun Belirtisi
PVA injection molded product weight fluctuates ±3%, exceeding the ±1% precision requirement
Neden Analizi
Unstable shot volume, inconsistent screw back position; holding time fluctuation; unstable feeding amount; PVA density variation ±2%
Çözüm
1) Displacement sensor to precisely control screw back position; 2) Stabilize holding time and pressure; 3) Precisely set the V/P switchover point; 4) Inspect density differences between batches
Temel Çıkarım
Product weight stability depends on shot volume precision and holding consistency
